Efficient sub array extraction [message #82425]

I'm using large 2D arrays e.g 30000 x 30000 and need to remove a 2D sub array for later processing e.g. Rows 30-700 and columns 100-10000.

Is there a more efficient way to do this than using subscript ranges?

For example?

Subarray = largearray[100:10000, 30:700]

The exact code I'm using is as follows:

A = [100,10000]
B = [30,700]

Subarray = largearray[A[0]:A[1],B[0]:B[1]]
